Does the force acting on a dam change if the area of water is increased?
Does the force acting on a dam change if the area of water is increased, but the depth remains the same?

Force = Pressure * Area for the total force acting across the entire dam.
You're talking about P staying the same but A increasing. So what happens to P*A?

If the surface area is increased but the depth remains the same, that means the mass of water is increased and therefore the force acting on the dam is increased.

Let's be clear what you mean by "force".
If you mean the force that acts at any given point, then no - it does not change.
If you mean the TOTAL force acting on the entire dam, then yes - the force changes proportionally to the linear distance where it contacts the water.
